Answer 1

While cooking, if the bottom of the vessel is getting blackened on the outside, it means that the fuel is not burning completely.

The fuel is not burning completely. The unburnt particles present in smoke blacken the vessel from outside. This is why, when cooking, the outside of the vessel's bottom became blackened.
